Would an extra 1970 powerhead help me with my 1975 115 HP?

[lawyertob]

I have an opportunity to get a 1970 115 HP powerhead for $50. I currently have a 1975 115 HP.<br /><br />I know that the coils and ignition or different, but I think the carbs and all the heads and such are the same.<br /><br />Am I right in assuming that all V4 heads and blocks of a give HP size are interchangeable. I have been told this, but have been unable to completely verify it.<br /><br />Will, this powerhead possibly provide me with anything useful?<br /><br />Thanks,<br />Joe

yes, The bore and stroke are the same. not sure if the heads and carbs are the same or not but for $50.00 you cant go wrong as you can part it out on ebay and make money if parts will not interchange.

tvpear12,<br /><br /> Thanks for the reply. If it was closer I would get it in a heartbeat, but it is almost 200 miles away, so it would cost as much to go get it as the darn thing costs to buy. If it was the right year, I would go, or if it was close...but off year AND long drive, I might pass on it.<br /><br />Thanks,<br />Joe

The bore of the 1970 115 is smaller (3.44 vs 3.5). Though the designs are very similar, not much interchanges between these motors. The V4 families are 1969-72,1973-77/78, and 1979+ (very roughly speaking).

Ledgefinder,<br /><br />Thanks for the reply, that is exactly the information I am looking for. <br /><br />I am basically looking for a powerhead that I could use hard parts off of. Things like heads, and even things like bypass covers or exhaust covers in case I break one somehow.<br /><br />I was thinking that the carbs might be the same, since they do use the same carb rebuild kits...but I know how rebuild kits can be somewhat universal.<br /><br />Oh well, at least I didn't spend the weekend driving to pick up a powerhead that wouldn't do me any good. <br /><br />Thanks again,<br />Joe
